A Patented Mar. 29,l 1932 UNITED STATES PATENT OFFICE- CHARLES E. KILGOITR, OF CINCINNATI, OHIO, ASSIGNOR T THE CROSLEY RADIO'COB- PORATION, 01T' CINCINNATI, OHIO, A CORPORATION OF OHIO RESILIENT SUPPORT FOR RADIO TUBES Application led February 12, 1927.- Serial No. 167,848.

It is the object of my invention to provide a resilient support for radio tubes or a radio tube which will tend to prevent shocks tothe A tubes or tube and to prevent vibrations set up by sound waves from being transferred to the radio tubes or tube.

A further object of my invention is the rovision of a mounting support which will Ee so shaped as' to yield a limited distance with the insertion therein of a radio tube and which will then rebound to a resiliently supported position. By means of the resilient support, the inertia of the tube will tend to make it remain in a fixed position regardless of slight vibra-tions which will be taken up in the resilient mounting.

Referring to the -drawings which I have disclosed -a preferred embodiment of my inventionz- Figure 1 is a front elevation of a portion of a. radiocabinet or casing wall showing my novel tube mountingplate in position.

Figure 2 is a section of the parts shown in 4Figure 1 taken along the line 2-2.

Figure 3 isa rear elevation showing the mounting support detached from the wall, with projections in two directions therefrom.

Figure 4 is a section taken along the llnes 4--4 in Figure 3.

Figure 5 is a plan of one of the mounting plates. Y

I have shown a portion of the casing or cabinet wall supporting the set at l. The

wall'l may be of metal as my mounting def vice does not require mounting on a dielectric panel. It has a circular orifice 2 extending through it within which the radio tube support is mounted. The support or mounting means for the tube comprlses 1n the preferred form illustrated, t-wo or more in sulating discs, 3 and 4, secured together as will be hereinafter described. The outer disc 3 has round holes 5, preferably in interspaced position as shown to allow for the insertion of the Contact pins extending from the radio tube as indicated in dotted lines at 6 in Figure 4. In aligned position with the holes' on the inner disc 4, there are a series of apertures 7 having rounded inner ends and-w squared outer portions. The resilient clips 8 against which the Contact pins bear are formed by inserting the bent ends 9 of the clips through the holes 7 and then securing the two or more discs together with rivets 10 which hold the disc together and also provide means for securing the discs on the resilient bracket 11 which secures the disc within the hole 2 in the wally 1. Th apertures 7 are squared where the tongues 9 pass down through them, thus holding the clips in p-lace.

The resilient bracket 11 for supporting the discs is preferably made from a unitary stamping shaped as shown in Figure 3. Ears 12 are extended from the outer periphery of a skeleton frame formed by the sides 13. The ears 12 have holes 14 with which the bracket may be secured to the wall 1 as by means of screws15. The ears lie in the` same plane as the disc 5 which supports the discs 4 and 5 in approximately the same plane as the wall 1 in which the tube mountmg device is secured. Another set of ears 16 extend inwardly from the side walls 13 of the skeleton bracket which ears serve to limit the inward movement of the plates during the interval when a tube is bemg inserted. rThe ears 16 are in a different plane than the ears 12 so that althoughfthe ears 16 serve stops they do not provide a means of transmitting vibrations from the wall 1 to the bracket.

For securing the discs to the skeleton bracket on the sides of the bracket opposite those occupied bythe ears 12 and 16,' a third set of ears 17 are extended inwardly from the sides upon a different plane than the ears 12 so as to allow for the thickness of thepiece 4. The ears 17 have holes in them through which rivets may be secured as indicated at 10. The

rivets 1 also serve to secure the two or more` From the above description, it will be obvious that I have provided mounting means for supporting a tube which will be simple to manufacture and which will very effectively take up vibrations, which might otherwise occur between the wall 1 and the mounting support. Modifications in the size and shape of the flexible bracket will readily occur to those skilled iii the art without departing lfrom the principle involved therein. It will further be obvious that a plurality of tubes may be mounted in a single resilient skeleton J frame made in laccordance with my invention.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. A resilient support for a radio tube vcomprising a plurality of discs of non-conof securing said discs to a member forming part of the casing for a radio set, said means tube mounting device, said supporting means comprising a skeleton frame member and diametrically opposed pairs of lugs, one pair of said lugs pointing inwardly and the other pair pointing outwardly, said lugs offset from said skeleton frame, inwardly projecting ears opposite the outwardly projecting pair of lugs, said ears serving to limit the motion in one direction of a mounting device attached to said inwardly projecting lugs.

6. Resilient supporting means for a radio tube mounting device, said supporting means comprising a skeleton frame member and diametrically opposed pairs of lugs, one pair of said lugs pointing inwardly and the other` pair pointing outwardly, said lugs offset from said skeleton frame, each pair of lugs lying in' a separate plane therefrom, and ears inwardly extending from said skeleton -frame opposite said outwardly extending lugs, and in the same plane as said frame.

comprising a resilient skeleton frame having ears serving as mounting means for said frame on said aforementioned member of said set and said skeleton frame being further provided with abutments against which said discs will abut during the insertion of tube terminal posts within said clips.

2. A support for a radio tube consisting of a non-conductive discihaving apertures therein for the insertion of tube terminals, said disc having resilient clips extending therefrom adapted to engage said terminals with the insertion thereof into the apertures in said disc, and a resilient skeleton bracket provided with mounting* elements extending from said bracket, and' means also extended from said bracket lying in the path of movement of said disc during the insertion of a radio tube.
